The Big Little Lies actress, 40, singled out the one item every woman should have in her closet. “I think it’s really important to have one dress that you know you look good in,” she said. “Make sure you ask your girlfriends. They know you look good, you feel good.”

Witherspoon’s style is impeccable, but she still asks for a second opinion before stepping out of the house. “I don’t ask [my husband Jim Toth] too much,” Witherspoon said of getting outfit approval. “I usually ask my 17-year-old daughter [Ava], ‘Does this look good?’ and she’ll be honest with me. She’ll be like, ‘No. You do not look good. You cannot wear that.’ So I depend on her brutal honesty.”

Witherspoon, who’s also mom of sons Deacon, 12, and Tennessee, 4, relies on social media to communicate with her kids. “I have two teenagers, and I have discovered that they will Snapchat me back, but they will not call me back,” she said. “And I think it’s important for people to communicate well with their children.”

The Wild star has recently been focusing on expanding her Draper James brand, which she called a “scary” challenge. “When we were raising money for the business, I had to go into lots of different meetings with different venture capitalists and I have to pitch the company and talk about the company, and that was a scary time because they don’t care who you are,” she said. “It’s whether your business is viable, whether it’s robust, and I think that was kind of the performance of my life.”

She added of the brand’s Southern feel, “I wanted to celebrate the tradition and the people who raised me and gave me so much of who I am.”
